How to get variable from component for put on the App.js

Even by searching on the internet I did not find, or in all that I did not understand.

My problem: I would like the "inputVal" variable found in the InputField.js component to be found where there is "!!HERE!!" in the App.js component(on the fetch).

Please help me - thank you for reading my message!

export default function InputField() {
  
  function handleSubmit(e) {
    // Prevent the browser from reloading the page
    e.preventDefault();

    // Read the form data
    const form = e.target;
    const inputVal = form.myInput.value;

    console.log(inputVal);
  }

  return (
    <form method="post" onSubmit={handleSubmit}>
      <input name="myInput" id="adress-field" placeholder="Enter adress" autoComplete="on" />
      <button type="submit" id="adress-button">Send</button>
    </form>
  );
}

import './App.css';
import AccountNumber from "./components/AccountNumber";
import InputField from "./components/InputField";
import { useEffect, useState } from "react"

function App() {

  //token fetch
  const [tokens, setTokens] = useState([])
  const [loading, setLoading] = useState(false)
  useEffect(() => {
    setLoading(true)
    fetch("https://api.multiversx.com/accounts/!!HERE!!/tokens")
      .then(response => response.json())
      .then(json => setTokens(json))
      .finally(() => {
        setLoading(false)
      })
      console.log(tokens); 
  }, [])


  function round(nr, ten) { // arondi un chiffre.
    return Math.round(nr * ten) / ten;
}

function numberWithSpaces(nr) { // formate un chiffre(x xxx xxx).
    return nr.toString().replace(/\B(?=(\d{3})+(?!\d))/g, " ");
}



  return (
    <content className="content">
        <div className="up-side">
            <div className="account-number-box">
                <p id="p-account-number">Total number of accounts</p>

                    {tokens.map(token => (
                      <tr className='token-row' key={token.id}>

                        </td>

                        <td className='center-column'> <p>${round(token.price, 10000000)}</p> </td>

                        <td> 
                          <p>{round(token.balance / Math.pow(10, token.decimals), 10000000)}</p> 
                          <p className='token-hold'>${round(token.valueUsd, 10000000)}</p>
                        </td>
                      </tr>
                    ))}

                  </table>
                </>
              )}


            </table>
        </div>   
    </content>
  );
}

export default App;

I not very good in react and i mak search on internet

You want to extend your InputField component to accept a callback function, that can be passed by your app:

export default function InputField({onSubmit}) {
  
  function handleSubmit(e) {
    // Prevent the browser from reloading the page
    e.preventDefault();

    // Read the form data
    const form = e.target;
    const inputVal = form.myInput.value;

    console.log(inputVal);
    onSubmit(inputVal)
  }

  ...
}

And in your App you need to pass that callback to your component:

<div className="adress-search">
  <InputField onSubmit={handleSearchSubmit} />
</div>

Note: Components are not consumed by calling them like functions.

In your App logic, you'll need another state to hold your search value:

...
const [searchValue, setSearchValue] = useState(null);

const handleSearchSubmit = (val) => {
  setSearchValue(val);
}

useEffect(() => {
    setLoading(true)
    fetch(`https://api.multiversx.com/accounts/${searchValue}/tokens`)
      .then(response => response.json())
      .then(json => setTokens(json))
      .finally(() => {
        setLoading(false)
      });
    console.log(tokens); 
}, [searchValue])
...
